Abstract: Prediction of thermal behavior and trajectory plays an important role in design and operation of stratospheric balloons. First, a more rounded and improved thermal and vertical trajectory model for performance prediction ...

Abstract: A brand-new concept of solar-powered airplane is brought forward in this paper. The special characteristics of such airplanes are sun seeking and eternal flight, which can consistently fly under the local daytime. The ...

Abstract: It is a challenging task to simulate the situation involving nonstationary motions, one crucial requirement of which is an efficient algorithm to realize the high-quality computational mesh deformation. The inverse distance ...

Abstract: Most unmanned aerial vehicles which fly with moving wings or encounter gusts at low Reynolds number conditions make pitching oscillation motions. The aerodynamic forces and flow field around the wings vary dramatically ...
